Product Overview 
  QDT low-speed plug-flow device, in the water treatment process, the widely used plug-flow oxidation ditch, all kinds of biochemical pool of mixing, but also can be used for freezing river, landscape water cycle and so on. Plug-flow speed is controlled by submersible motor, speed reducer, leaf pulp and install system components. Its characteristics are supporting small power (1.5-7.5KW), low speed (36-135R/MIN), pulp leaves large diameter (1000-2500MM), low-speed rotation, resulting in a large volume of flow, wide range of services. Swept-style banana leaf pulp design, with self-cleaning function, the use of molded polyurethane or aluminum alloy casting, with a light weight, high strength, corrosion resistance and other characteristics, its excellent friction performance, ensure that low-speed motion state and the liquid to produce good damping effect, thereby creating a gentle flow of water, push the series in addition to the role of water flow and create, but also with agitation
